ADJUSTABLE SIGNAL-BLOWER.

Specification of Letters Patent.

Patented Ian. 19, 1909.

Application filed June 2, i905. Serial No. 263,380.

To all u'wm it may roncrrn: l

Be it known that l. lnxrsr O. Liwrox, of l^`ii;hl.,nrg. in the eoamy of llorccstrr and 'finie ot' Massachusetts, have invented cerlain new and useful lmprovmnents in Adjustable Signal-llmvers: and'l do hereby declare that the t'olhuving is a full. clear, and exact description ot the same.

This invention relates to signals and par- Iir-nlarly to adjustable audible signals and meansA for operating them.

An object of this invention is to provide nofel' means for blowing a horn` the said means being lmrlicularlf. designed for use in vehicles of the aitomobile type. whereby the device may be stationed under the lloor of iin; rehiele body. an operating rod or handle being the only visible portion above the floor. .5 As to the point ot' atiaelnncnt of the operatin;r mechanism. it is an innnaterial feature, i as i in '.'e provided means for adjusting the l bpm-:ning rod or plunger to suit particular l i'm,zii1'eiiieixts. i

A further object of this invention is to provide a bellows or other compressing' mea ns so constructed as to prolong the durability of the material from which itis formed, and l provide novel means whereby the compressed may be conveyed from the compressor to any suita'ile pointwhere the sounder or horn is stationed.

Finally an object of this invention is to produce a device of the character described. which will `prove etlicient and satisfactory in use. comprislng comparatively few and inexpensive pf ts, and simple. in construction.

Vl'ith the foregoing and other objects in i View, the invention consists in the details ot' construction and in the arrangement. and combination of parts to be hereinafter more fully .-et forth and claimed.

In describing the invention in detail reference will be had to thc accompanying drawings forming part of this specification wherein like charartL-Ls. denote corresponding parts in the several vie s, in which- Figure .1, is a view in perspective, of tle easing and the compiessor operating means with the horn and connection to the compressor. Fig. 2, isa view in elevation of the easing broken away to show the compresser mechanism. Fig. 3. is an end view of thai; compressor casing and coupling. Fig. 4, is

n plan view with the top of the casing removed.

in these drawings A. denotes the casing, one end ot' which is provided with a vertically7 disposed slot B. through which the arm (l. projects, and in which the Said arm iS slidable.

ll'ithin the casing and on the bottom thereof l provide a frame l), forming one portion of a bellows and to this frame I hinge. a'top E. through the medium of the hinges l".

The side and front edges of the frame D, and top E, are connected by a flexible wall G. which permits the [op to descend with relation to the frame D. thereby compressingr the air and forcing it out of the coupling ll, which coupling is here shown as an L-shaped pipe ha vingr its upper end attached to the casing A, in any suitable manner,it being` understood that the said coupling is in comuumieation with the interior of the bellowsheretofore described.

The. arm C, is attached to the top E, of the bellows and its movement is communicated to said top for the purpose of depressing it and the said top is held normally elerated through the mediana of the Spring I, which has one end connected to the arm C, and the opposite end connected to the crossarm J, which is supported by the sides of thc easing.

The. top of the bellows is also held elevated through the medium of the sprinf,r K which is arranged internally of the belloi's on thc studs L, which actas guides.

'The outer end of the arm C, 1s provided with an aperture through which thc rod M, is adjustable, itheingf understood that 4the lower end ol' the said rml is threaded for a suitabledistanee to permit thc adjusti ment. of the nuts, N, and X', stationed on opposite sides of the arm. lf, therefore the casingr containing the compressor is secured to the frame of the vehicle, the said casing` may be positioned at a greater or less distance from the floor of the vehicle and the rod may be adjusted to project through the said Hoor by reason of 'the provision of the nuts indicated.

lt will he observed that. the rod may bc shortened in like manner :md therefore this compressor, may be changed as slated, to suit particular requirements. The head or plunger bodyO, is threaded or otherwise removably secured to the rod to permit the f sind rod to pass through u small opening 1n slet in one end, a bellows in the casing, said bellows having opposed studs on the inner feces of the walls thereof, a s ring engnging the studs and holding the be lows normally distended, au air outlet tube, an arm secured to the. upper face of the bellows and extending through the'slot, a cross arm secured n'ilbin the casing uL-'ive the bellows, a spring secured to said cross arm and the bellows to further hold the bellows distended and an adjustable lod carried by tbe arm on the bellows whereby the operation of the bellows may be regulated.
